Yüksek ısı transfer kabiliyeti, enerji absorbe edebilme ve ses izolasyonu özelliklerinden dolayı kafes yapılar havacılık, otomotiv ve biyomedikal sanayii başta olmak üzere bir çok alanda kullanılmaktadır. Kafes yapıların bu kabiliyetleri üzerinde farklı proses ve geometrik parametreler etkili olmaktadır. Farklı endüstriyel uygulamalarda, ilgili kafes yapısının uygun proses ve geometrik parametreler ile birlikte kullanılmasının, uygulama sonucu elde edilen verimi arttıracağı bilinen bir gerçektir. Bu çalışma, Taguchi deney tasarımı kullanarak, kafes yapılarda, kafes yapı çeşidinin, inşa yönünün ve hacim oranının, üretimden sonra parçada meydana gelecek çarpılma, yüzey pürüzlülüğü ve duvar kalınlık değişimi üzerindeki etkisini deneysel olarak incelemeye odaklanmıştır. Üretim için lazer toz yatağı füzyon yöntemi ve CoCrMo malzeme kullanılmıştır. Her bir parametrenin çarpılma, yüzey pürüzlülüğü ve duvar kalınlık değişimi üzerindeki etkisi ve optimum parametre seti, değişkenlerin analizi (ANOVA) metodu ile bulunmuştur. Yüzey pürüzlülüğü için en optimum parametre seti elmas kafes yapısı, 0,2 hacim oranı ve 90o inşa yönü olarak belirlenmiştir. Duvar kalınlığındaki değişim için ise en optimum parametre seti gyroid kafes yapısı, 0,4 hacim oranı ve 45o inşa yönü olarak belirlenmiştir.
